ROOF CONSTRUCTION.

Application filed May 27,

This invention relates to roof construction and particularly to the method and means for the fabrication and putting into place of arched roofs having the structu `al characteristics of the roof and walls disclosed in.

One of the objects of the present invention i is the construction of such a roof, particularly for buildings of considerable height or length in which the use of scaffolding or other temporary supporting means or appliances is obviated. a

Another object of the invention resides 1n the construction of a sectional roof in which the first section serves as a centering or supporting unit upon which the other sections are fabricated and then moved into position.

A further object of the invention resides in the method of acconjiplishing the above result.

Other objects of the invention will appear as the following description of the preferred embodiment thereof proceeds.

1n the drawings Figure 1 is a cross section through the first-built or centering section .of the roof, the ends of the walls being shown. upon which it is supported7 and showing also another section being erected on top of the ii rst i section.

Figure S is a cross section. taken along the line 8 8 of Figure 4l. v Figure 9 is a fragmentary cross section taken along the line 9 9 of Figure 5, and

Figure 1() is a fragmentary cross section taken along the line 10-410 of Figure 5.

)teferring new in detail to the several iigilres, the numerals 1 and 2 represent opposits retaining walls on which are supported the sills 3 and i of the first-built or centering section of the roof, the same being represented in general by the reference character 5. Said section is constructed with a reticulated framework comprising lamella C disposed angularly towards one another, the ends of two lamallae which are substantially in a straight line and meeting adjacent the middle of a lamellarunning angularly thereto. This arrangement of lamellae is fully disclosed in the patent to Zallinger hereinbefore mentioned, and in itself does not form a part of the present invention, since the principles of the invention can be practiced with roofs having a variety of forms of framework construction.

' The first or centering section is constructed in t-he usual manner, presumably upon suitable scaffolding, not showm'and after the frame work has been fabricated, it is covered with sheathing strips 7 to the extent indicated in Figure 2, the ends S of certain lamelles being left free to join with the lamelles of the adjoining section after the latter has been made and moved into its liual position. One strip of sheathing on cach side of the centering section is omitted as shown at 9 in Figure 5, the purpose of said omission being to afford room for inserting the hooked ends of the hangers 10, shown in Figure 9 so that thelatter may rest upon the upper edge of the next lower sheathing strip. The height and width of the arch of the first or centering section are preserved in the usual manner by means of tie rods 11 coacting with Wedge blocks 24C upon which the sills 3 and 4; rest.

The second, and subsequent sections are similar to the iirst section, but put together upon it and afterwards shifted into final porof the centering section, said hangers being furnished with rollers 16. .The sills 17 of the second section are spaced in proper lon gitudinal position on the hangers 10, a removable track strip 18 being temporarily secured to said sills and bearing against the rollers 16. Said rollers are designed to take the thrustof the arch. The reticulated lamella framework is then built up` being secured to the sil s and resting upon die bat- :tens 13, ll and 15 giving to the second secv tionthe same shape 'astbe lirst or centering section. The framework thus formed is denoted by the reference character 19 in Figure 2. Y i

vIt is zpparent that the second section, after the blocks 13, liet and 15 havey been removed `relies entirely :for thc retention of its shape upon/the counterthrust*of*the rollers 1b. It is to be understood, hor-Jever, that. this counterthrust holds lthe arch against lateral eX- pansion only, it being obvious that When'the second section entirely unsupported by the centering section the Weight of the arch Will cause a longitudinal elongation of the saine due to the lazy jack action of thelamella so that provision must be made for temporarily holding the arch ofthe second section from longitudinal spreading with consequent flattening. This is done by the provision of removable tica-ods 21, Figuije 2, which have hooked ends adapted to engage in the angles of the lainella. It is conteniplated now to roll the superposedsection Y loruritudiinillv otl of the underlying section.

This is done gradually by any suitable means of power application, not shown. l/Vlicn the end of the second section begins to overhang the end of the centering section fa tie-rod 11, Figure 5, is put in, and as the overhang iiicreases other tie-rods are putin place preservingthe shape of the arch. As the second section is rolled longitudinally off from the centering section it isV supported upon'carriages 22, oneof which is represented in de tail in vlligure 10, consisting essentially of aV yoke member carrying a roller 23. The carriage is here shown as conveniently resting under one of the Wedge blocks 24E. The roller 23 preferably engages a track strip 26 laid `longitudinally upon the Wall ofthe build,

ing. It may be found necessary, to ensure the vertical position of the carriage, to pro-i i vide bracing means such as the Strut 27 shown in Figure 10 secured to one side of the carriage, and temporarily 'to one of the lainellse. lVlien the second section has been entirely Vremoved from the centering or underlying section and is in the final position in which it is to reside, jacks, one of `Which is illustrated at 28 in Figure 6, are" placed beneathit and elevated so as to ta-lrevthev Weight of the `arch from the carriages. In the present instance the frontlayerof bricks in the wall has been removed to receive 'the jack so that when the screw ofthe jack is lowered and sillof vvthe arch will rest `upon the retaining wall. then the Weightl ofthe arch has been transferred tothe jacks on `one side :of the arch the carriages on that 4side are removed and the jacks lowered until the arch rests upon the-Wall. The same operationv is then repeated for the other side ofy the section. y'If there isany misalme'ment in;

the position of the secondY section relative to the walls or to the centering section, the turnbuckles in the tie-rods 11 and 11 may be adjusted so' as to draw in the ends ofthe arch or permit them to expand. When thc centering` section and the adjacent section` are in proper alinement the nnsheathed lainella 8 of one section are bolted or otherwise secured to the complementary lamella of the other section and the two V sections ofv the roof thus united. Any number of rootsections inay be made in this Way, consisting of standardized parts and eliniiinatin-g the need" of scaffolding or other supporting means except in the building of the irst'or centering section, great economy in the cost of building a roof being, thus obtained. Y

Although I have in the present embodiment of the invention shown a roof made with wooden lamella, it is to be understood loo that the invention may be practiced with' equal success with roofs having commercial iron frameworks. l

lVhile I have in the above dcscriptiondisclosed what I believe to be a preferred and practical en'ibodiment of my invention, itis to he understood that the specific details described are not limitative in their effect upon the invention but merely illustrativeI except in so far as theyare expressly prescribed by the terms of the appended', claims.

Having described my invention .what 'I claim as nenr and desire to secure by Letters Patent, is

1. The method of constructing vthe 'sub-r sequent sections of a sectional arched roof one of the sections of which is already constructed which consists inybuildingfa subsequent section upon the already builtvsfections, supporting it thereupon, rshifting the subsequent section relative to the already built section until it overhangs the latter, placing a tie-rod across the ends ofthe overhanging portion to hold the shape of the arch, and continuing the shifting operation and placing the tie-rods until the second section has reached a final position along side ot the already built section.

Q, The method. of, constructing the subsequent sections of a sectional arched rootI one of the sections of which is already con structed which consists in building a subsequent section upon the already built section, supporting it thereupon, shifting the subsequent section relative to the already built section until it overhangs the latter, placing a tie-rod across the ends of the overhang-ing portion to hold the shape of the arch, continuing the shitting operation and placing the tie-rods until the subsequent section has a reached a linal position along side of the already built section, and simultaneously with the shitting, and transferring the subsequent section to carriages.

3. The method. of constructing the subsequent sections ot a sectional arched roof one ot the sections of which is already constructed which consists in building a subsequent section upon the already built section, supporting it thereupon, shifting the subsequent section relative to the already built section until it overhangs the latter, placing a tie-rod across the ends ot the overlmnging portion to hold the shape of the` arch, continuing the shifting operation and placing the tie-rods until the subsequent section has reached a linal position along side of the already built section, and simultaneously with the shifting, transferring the subsequent section to carriages, substituting jacks for the carriages, and lowering' the subsequent section to its permanent means ot' support.

4f.. The method of constructing the subsequent sections or sectional arched root, one et the sections ot' which is already constructed which consists in arranging battens longitudinally of the already built section ot such height as to contorni to the degree of curvature of the subsequent section when built and that of the already built section, building a subsequent section upon the already built section, supporting it upon said battens, and shifting the subsequent section to a final position along side of the already built section.

5. The method of constructing the subsequent section of a sectional arched roof one of the Y sections of Which is already constructed which consists in arranging battens longitudinally oi said already built section, said battens being of such height as to contorni the degree of curvature of the subsequent section when built to that of the already built section, arranging counter-thrust members upon said already built section to receive the ends of the arch of the subsequent section, building a subsequent section upon the already built section, supporting it upon said battens and said countenthrust ineinbers, and shifting the subsequent section to a iinal position along side of the already y built section.

The Inethod ot constructing the subsequent sections et a sectional root of reticulated lainella construction one ot the sections of which is constructed With longitudinal hanger receiving slots adjacent the sills and which consists in placing hangers in said slots Awith casters exteriorly of the first section, placing the sills of the subsequent section upon the casters, building the subse quent section on its sills to be supported through the hangers and by the already built section, placing longitudinal tie-rods to prevent longitudinal spread of said section, shifting by longitudinally sliding on the casters of the hangers the subsequent section relative to the already built section until it overhangs the latter, placing tierods across the ends of the overhanging portion of said subsequent section as it is progressi'vely shifted to hold the shape of the arch, and continuing the shifting operation until the subsequent section has reached its final position along sid-e of the already built section.

ln testimony whereof I have hereunto set my hand.
